Array-type ultrasound therapy system

An array-type ultrasound therapy system, wherein the ultrasound therapy system comprises an ultrasound therapy control unit, an ultrasound transducer driving array, and an ultrasound transducer array;

• the ultrasound therapy control unit is provided with a field programmable gate array (FPGA) unit, which is separately connected to a detection signal output end of an ultrasound transducer configured to detect ultrasound echoes generated during an ultrasound therapy and an input end of the ultrasound transducer driving array, and the FPGA unit is configured to receive therapy parameter that is set manually and output therapy content for displaying on a display unit;
• the ultrasound transducer array comprises n ultrasound transducers, wherein n−1 of the n ultrasound transducers are configured to perform ultrasound therapy, and remaining one ultrasound transducer is configured to detect ultrasound echoes generated during the ultrasound therapy;
• the detection signal output end of the ultrasound transducer configured to detect the ultrasound echoes generated during the ultrasound therapy is connected to a feedback signal input end of the ultrasound therapy control unit;
• a control signal output end of the ultrasound therapy control unit is connected to an input end of the ultrasound transducer driving array, and an output end of the ultrasound transducer driving array is connected to a driving end of each of the ultrasound transducers configured to perform the ultrasound therapy;
• and
• the ultrasound therapy control unit is configured to predict a probability of hot spot generation in an ultrasound therapy process according to the ultrasound echoes and adjust an amplitude or timing of a phased digital signal according to the probability of hot spot generation so as to adjust an intensity of therapeutic sound or a deflectable focusing point of the ultrasound transducer array.
